Your arguments could be nitpicked, but lets skip that and just take as a given that you are 100% correct. That doesn't change the fact that helium is a non-renewable resource. Conservation makes sense. Maybe it won't matter to us today, or even in 40 years. But it will matter to someone else in 140 years.
In my mind, any decisions made based on markets are a short-term strategy. If a resource is non-renewable, I prioritize conservation. Where practical, I use renewable resources.
True of energy, but not of helium. Fusion produces a lot of energy from very little fuel. Running the world on fusion would supply a tiny fraction of our helium demand.
